Binder, Bridge Deck is a two - component, low viscosity, low modulus; epoxy binder formulated
specifically for protective overlay applications. Blended with suitable aggregate, Honest Binder, Bridge Deck
mortar, slurry and aggregate broadcast systems protect concrete and steel decks from wear and intrusion of
damaging chemicals (aircraft and vehicular fluids, deicing compounds, etc.). Honest Binder, Bridge Deck
utilizes controlled flow viscosity for application of thick films on uneven or sloped surfaces. High aggregate
loading, short cure cycle and low modulus mechanical properties make this binder ideally suited for a variety
of overlay applications. Each type of installation may have specific application and performance
requirements. Evaluation of trial mixes particularly under low temperature conditions prior to installation is
recommended.
Features
Convenient 2: 1, by vol. mix ratio
Fast cure for short downtime
Controlled flow for uneven/sloped surfaces
Does not embrittle; stays tough and flexible
Resists road, auto and aircraft chemicals
Environmentally safe- No VOC solvents
Limitations: Substrate surfaces must be dry. Minimum
installation and cure temperature is 50 deg F. Maximum
thickness of approx. 1 inch per lift. Do not add solvents or
otherwise thin this material.
Packaging & Colors: Standard package sizes of Part A +
Part B are 3 and 15 gallons. Color is Clear dark amber; custom
colors available
Shelf Life: Three years minimum in unopened, original
containers when stored between 60 and 90 deg F in a dry
place away from sunlight.
Chemical Resistance: Resistant to a wide range of
commonly used deicing chemicals and aircraft and automotive
fluids. It has limited resistance to hydrocarbon solvents.
Performance is a function of the specific chemical and
concentration, ambient end solution temperatures, exposure
times and housekeeping procedures. For information on
specific chemicals and exposure conditions, contact a
ChemCo Systems, Inc., technical representative.
Surface Preparation: Substrate surfaces must be dry, sound
and free of all bond-inhibiting substances. Damp and wet
surfaces must be dried with artificial heat prior to installing the
product. Prepare surfaces in accordance with ASTM D 4259
or ACI 503R and ChemCo Systems' specific
recommendations. Cleaned concrete surfaces should have a
minimum strength of 250 psi in direct tension. Steel surfaces
should be cleaned to "white metal" according to SSPC SP 5.
Prepared spells and surface defects may be filled with a CCS
Binder, Bridge Deck repair mortar (see below) before overlay
installation.
Aggregate Selection
Overlay and repair mortars: The preferred aggregate for most,
kiln-dried, graded and bagged. The sand particles should be
round to sub angular in shape. A good gradation for low void
content is a 2:1 or 3:1 blend of #12 or 16 mesh and #70 or 90
mesh. If using a single sand fraction, a #20 or 30 mesh is
recommended.
Slurry coat and Multiple layer broadcast systems: The
recommended aggregate size is #6 x 12, 8 x l6, 12 x 20 or 20 x
40 mesh depending on the installed thickness. Vehicular
surfaces: For maintenance of long-term skid resistance,
consider use of polish-resistant aggregate such as aluminum
oxide, silicon carbide, blast furnace slag, trap rock, etc. For all
applications, the maximum particle size of the aggregate
selected should not exceed 1/3 of the installed thickness.
Mixing: Honest Binder, Bridge Deck is a two-component system.
The resin to hardener (Part A: Part B) mix ratio is 2:1, by
volume. Premix the individual components before drawing from
bulk packaging. Wear safety glasses and clean neoprene
rubber gloves when handling the material. Transfer the
appropriate quantities of Part A and Part B into a mixing
container. Use quantities that can be applied before the pot life
of the mixed material expires. Blend thoroughly using a Jiffy
mixer blade attached to a low speed (350 - 750 rpm) electric or
pneumatic drill. Proper mixing will take 2 - 3 minutes. For fluid,
epoxy-rich mixtures continue mixing and slowly add aggregate
to the mixing vessel. For less fluid, epoxy-lean mixtures, transfer
the mixed binder into a mortar or plaster mixer, add aggregate
(coarse first, fine last) and mix an additional 1 - 2 minutes.
Installing
Overlay and repair mortars: Prime the substrate with mixed
binder components at a thickness of 8 - 10 mils (160 - 200 sq
ft/gal). Apply the epoxy mortar to the primed substrate while the
primer is still tacky. The mortar may be rodded, tamped,
screeded or troweled into place. Clean application tools
frequently.
Slurry coats: Blend 1 part by volume of premixed binder and 2 -2
1/2 parts by volume of aggregate in a mortar mixer for 2 - 3
minutes. Apply the slurry in a thickness of 3/8 inch and strike-off
with a screed bar. Broadcast additional aggregate (10-14 lb/sq
yd) into the surfacing until all wet spots are gone. Allow to cure 6
- 8 hours, remove excess aggregate by sweeping and open to
traffic. (Continued on next page)

Installing (cont.)
Multiple layer broadcast systems: Apply mixed binder at a rate of approx. 45 sq ft/gal by roller, squeegee or spray. Uniformly
broadcast aggregate (8 - 10 Ib/sq yd) until no wet spots are visible. Allow curing for 2 - 5 hours. Remove excess aggregate by
sweeping. Apply the second coat at approx. 30 sq ft/gal. Broadcast aggregate at 12 - 14 lb/sq yd. Remove excess after 2 - 5 hour
cure. Repeat process. if necessary to build-up to the specified thickness. Allow extra cure time for the top layer (4 - 6 hours). Remove
all excess aggregate by sweeping and open to traffic.
Clean up: Excess mixed product is best removed from the work area and tools before it hardens. Use of rags and solvents, such as;
acetone or heavy-duty detergents facilitate cleaning. Cured product may be removed from tools by soaking in an epoxy stripper.
